With a high-friction anti-skid bottom and almost 2 pounds of weight distributed around its base, the Dash-Mat keeps your in-car electronics securely on your dashboard. It's perfect for vehicles with steeply inclined windshields or unusually shaped dashboards. The Dash-Mat has an adjustable clamp with spring-loaded arms that open up to 3 3/4. When you leave your vehicle simply move your Dash-Mat mounted electronics out of sight. Your electronic devices will be out of the sun, won't tempt would-be thieves and there's no tell-tale suction cup mark on your windshield.
